In the fibroid-blasting Sonalleve, a half-sphere-shaped transducer array squats beneath the imaging table. By contrast, for the breast system, Philips says it built a ring structure that lets the transducers fit around the breast, so ultrasound energy can come from multiple directions to build the focus in the tumor. This set-up reduces the risk of burning the skin, Philips’ Andreae says. By maximizing the amount of skin surface exposed, each bit of skin heats up less.

“Non-target tissue only rises a few centigrade above body temperature,” he says. “At maximum, a mild skin reddening (appears) and not more than that.”
